-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 If you are not booting from the GPT disk, you don't need the EFI partition (or any special boot partition). The required backup FAT is usually put at the end where there is usually some free space anyway. It has been a long time since I've converted from MBR to GPT, but it didn't require any resizing that I remember. I'd test it in a VM or similar to make sure you understand the process. You will also have to manually add the Ceph Journal UUID to the partition after the conversion for it to all work automatically. - ---------------- Robert LeBlanc PGP Fingerprint 79A2 9CA4 6CC4 45DD A904 C70E E654 3BB2 FA62 B9F1 On Thu, Jan 14, 2016 at 9:00 PM, Stuart Longland wrote: > On 12/01/16 01:22, Stillwell, Bryan wrote: >>> Well, it seems I spoke to soon.
